TO ALL WHOM IT MAY CONCERN:

Be it known that we, WERNER Sinn-MENS and J onlin-N Gaone HALsKE, of Berlin, in the Kingdom of Prussia,

have invented certain new and useful Improvements in Spirit-Meters; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the annexed sheets of drawings, making a part of the same.

The ppi-pose of our apparatus is to measure the volume of pure alcohol which flows through it, independent of the volume of spirit in which 'the same is contained, and, at the saine time, to measure the volume of the spirit itself. To this end, although the countcrwork for the pure alcohol is set in motion each time that a certain measured quantity of spirit passes through, it is,.nevertheless, only advanced by so much as corresponds exactly with the volume of pure alcohol contained in it. This corresponding indication is attained by means of a curve turning upon the axis ofthe irstwheel of the counterwork, which strikes against an index moved up and down by means eftan alcoholometcr, so that the indications of the aleoholometer and its index prescribe the limits of thc angles through which the curve, andthcrefore the ceunterwork, of the apparatus can turn.

The principal parts of 'the apparatus are as follows:

.' The drum G. The vessel N, in which the alcoholometer .P hangs, The spring system Y Q, withlever .S and index T.

The iniiux arrangement a ed e and eiliux system fg h 7c. .'.Thc trcfoil U. I

The angular lever V, with the curve X, ratchet-wheel s, and click-springs. lhle counterwork for pure alcohol r r 1' 1"'1'; and The counterwerkfor spirit o o o o 0. The measuring-drum/G is made of galvanized sheet copper. It is divided into three compartments, I, II, and III, each of which, at a temperature of 60 Fahrenheit, contains one gallon, so that the whole drum contains exactly three gallons. 'The spirit, which iiows into ther'lrum through the central cylinder K, enters the mcasuring-compartments through the slits a a a,`and leaves them through the iat tubes I) b Z1. The measuring-drum turns upon the axis J, in hearings in the two side pieces of the frame A B C. The latter is supported in the rectangular copper trough lL, which stands upon thc sole-plate D, and whose purpose is to receive the spirit as it leaves the compartments of the measuring-drum. The spirit flows into the measuringdrum through thc tube II, 'reaches the-inncr-cylinder K by means of the annular chamber 1, the under side of which is pierced with numerous holes to allow the spiritto low regularly into the central cylinder, and which is so supported vthat the drum turns around it and the axis within it without friction. The cent'rc of gravity of the drum, when cmptyrles in the axis. The compartments, however, are so constructed, that, upon the inilux o spirit into a compartment, the centre of gravity of the whole system lies under the axis, and tends to move it slightly, towards the loft hand, by reasonl of which the drum turns suliicicntly to lift the influx-slit, through which the spirit at-the moment iiows, above, and simultaneously to depress that of the next following lcompart ment below, the surface. The flow into the first compartment ceases therefore,'and that into the second begins. By this means the centre of gravity of the drum is moved further towards the left, by reason of which the drum makes quickly one third of a revolution, pouring out-the spirit from thc first compartment into the trough L, and bringing the centre of gravity again under the axis.

2. On the bracketE is the cylindrical mixing-vessel N, which receives, through a system of supply tubes, a e ol e d e', the spirit which is to be measured before it passes through the tube I-l into the measuring-drum.

,The aleoholometer P hangs inthe middleof this vessel. It is constructed of thin sheet brass,in the form of two flattened sphcroids, one on the other, and is filled with strong alcohol and hermetically sealed. Its purpose is, first,.to guidethe index T, and, secondly, by its greater cocllicient of expansion, to compensate the effects of variations iu'tcmperature. The form of this alcoholometcr iioat is such as to allow of a considerable expansion and contraction, according as its temperature rises or falls.

' 3. The aleoholometer swimmer is supported in the mixing-vessel partly by the spirit which flows through the apparatumand partly by the spring system Y Q, the deiicetions of which are communicated by the inter'- vcning coupling fr A with the arm S, which is fixed upon the same axis as the indexv arm T. Thus the indications ofthe alcoholometer are brought up tothe curve U, which strikes against the index. The spring system consists of three parts: the inflexible arm Q, which is connected with .the flat spring 1/ and the screws Y, for adjusting the height as well as the length of the spring.

4. The mixing arrangement a c d e is employed in order to counteract the tendency of the spirit to separate into strata in the vessel N. In its construction advantage is taken ofthe difference between the specific gravity of` the various strengths of alcohol which leave the condenser, to conduct the heavier or weaker spirit inte the mixing vessel above, and the lighter or stronger spirit underneath the alcohol swimmer. When weaker spirit than the mean of' that in the mixing-vessel reaches the chamber I' of the condenser through the tube a, the same will, by reason of its greater specific gravity, fall into the inner concentric compartment E, and rise, through the tube c, into the ring e', which is, on its inner side, pierced with holes. The sections of these holes increase in size the further they are from the junction of the ring with the tube e. The purpose ot' this is that the infiux of the spirit may take place equally` around the whole mixing-cylinder. If, on the contrary, stronger spirit than the mean of that in N reaches the vessel F, it rises, by reason of its smaller specific gravity, through the tube c to the mouth n., falls into the funnel A, and flows from this through the tube d into the rinr d', which is constructed similarly to c'. The two arms fg of the eiilux arrangement j" gfg 7i 7c are intended to insure spirit of mean strength reaching the measuring-drum. f and g are rings constructed inthe same way as d and e. The spirit passes from them, through the tubesf and g, into the central space 7c, from which the mixture of heavier and lighter spirit flows through the tube h, funnel Q, tube II, and annular chamber J into the inner cylinder K of` the measuring-drum.

5. The metal trefoil U is fixed upon the axis ofthe measuring-drum and turns with it. Its form is that of a circular disk, cut out at three peints into deep bellows at distances of one hundred and twenty degrees from each other. It is placed upon the axis, so that during the time one of the compartments is being filled, one of the leaves of the trefoil stands upwards and holds back the curve. On the left-hand side of this arrangement is 6. The angular lever system V, whose axis, in the arm Z, is, at the same time, axis of the first wheel of the counter-work. The lever V has, at its further end, a jockey-wheel, R, which is lifted upon the periphery and falls into the hollows oi' the tref`oil U. Two systems of click-springs, upon 9 and G, engaging with the teeth of the ratchet-wheel f, cause the latter tremain stationary when the jockey-wheel falls into a hollow of' the trefoil, and to turn correspondingly with the curve when it is lifted again upon the periphery. The divisions of the curve are so arranged that, first, when pure alcohol passes through the apparatus, the index T takes such a position as to allow the curve and cou terwork to turn through an angle of thirty-six degrees; the index has, in this case, its highest position, and points to 100 on the curve; second, when water at 60 Fahrenheit flows through, the index touches the curve at 0, and prevents the jockey-wheel from falling into the hollows of the trefoil, and, therefore, the counterwork from turning; third, when spirit of n volumes per cent. passes through the apparatus, the curve strikes the index in that point which allows the angular lever, ratchet-wheel, and counterwork to turn through 36,560.

'7. The rotation of the first wheel 9 of the counterwork is communicated to the remaining wheels r', 1,1 and rm', in the usual way, by means of intervening pinions. The apparatus is therefore able to measure the volumeof pure alcohol which passes through it, whatever the strength of the spirit may be in which it is contained.

8. The lower couuterwork o o oH 0 0" measures, on the other hand, the entire volume of the spirit. The first wheel o of this system is therefore attached directly to the axis of the measuring-drum. Each of the counterworlis is graduated from one to ten thousand gallons. l

By reason of the peculiar tripartite formation of the measuring-drum, its measurements are independent of the velocity of' the spirit er fluid which enters it, which is not the ease with any of' the spirit-meters heretofore made; and, moreover, the drum by this means is enabled, during its rotation, to exert suflicient force to set the curve and counterworlrs in motion without the measurements losing anything in exactness.

This tripartite measuring-drum, with its springing motion, is especially adapted to indicate the quanty of' the spirit passing through thc meter, by drawing oil' a sample of the same in such manner that while the volume ot' fluid is being measured, a quantity completely proportional to such volume is furnished for testing purposes.

The principal parts of this simplified apparatus are (as shown in Sheet V)- 1. The measuring-drum G, above the trough L.

. The tcst-tubes p pp, with the aperture D, at the sidi` ot' trough L..

. The vessel A for receiving the sample.

. The indicator for the volume of the liquid.

The drum G is, in a working apparatus, made of tinned copper sheathings. The internal arrangement and functions of the different parts of the drum are entirely similar to those of' the drum hereinbefore described, and the compartments so far correspond in size, that, while in the first-mentioned apparatus they are each adapted to contain one gallon, here they contain 0.1 gallon. The cylinder K, however, differs in construction from that previously described. In the apparatus now under consideration it projects 1.1 inch to the front for the purpose of enabling the test or sample to be withdrawn from it, and the spirit conveyed or passing from the cooler enters it immediately. The fluid runs through the trough L and is discharged at M.

2. Upon the periphery of that portion of` the cylinder K which projects from the drum there are three tubes, p12/p, of' suitable calibre, and ot' equal diameter, (0.1 inch,`) with corresponding or similar curves, and 'having the same or corresponding positions with respect to the periphery of the cylinder. 'Their inner ends are attached to the cylinder, so as to correspond, respectively, in position to the apertures u a a, through which the spirit, as above explained, passes to the compartments of the drum G, and their enter ends have the same relative position with respect to the points where 'they are attached to the cylindenas the openings hold to the openings a 11., It is obvious, therefore, that the tubes are lled in the same proportion as the drum, a small sample or test quantity of the spirit being thus obtained, which is proportionate to the volume of the same which 'is being measured. The pocket or smaller trough D, attached to the lside of the trough L, receives the sample, and conducts it through theltube 'm'into- 3.3 The trough or vessel A, which serves, at vthe same time, as a base or support for the apparatus. 4. The rotation of the first wheel of the indicator is produced, as shown in the drawing, by direct communicationwith the axis of the drum, so that the volume of spirit which passes during one rotation of the drum will be clearly marked by the indicator.

Having now described our invention, `and the manner in which the same is or may be carried intoefect, what we' claim, and desire to secure by Letters Patent, is

1. The .measuring-drum, constructed and arranged as herein described, so as to rotate with a springing motion, that is to say, provided with threeu compartments so formed that' the centre of gravity of the spirit during its influx into said compartments shall liel in a vertical plane, passing through the axis of the drum, substantially as shown and set forth. v A' 2. The alcoholometer, in combination with its indexy and supporting spring, substantially as and for the purposes herein shown and specified.

3. The mechanism herein described for imparting to `the counterwork a motion which shall at all times be proportionate 4to the volume of pure alcohol contained in the spirit Vor liquid which passes through the measuring apparatus.

4. The combination, with the'mixing-vessel N, of the pipes or tubes for the induction of the spirit orliquid, arranged as described, so that when spirit of varying strength is conducted into said vessel, the heavier shall enter above and the lighter below the alcoholometer, substantially as and for the purposesl set forth.

5. The combination, with the'measuring-drum and interior cylinder K, of the mechanism for obtaining a sample of thespirit proportionate in quantity to the volume of the said spirit which is measured, arranged and operating substantially as set forth. i

In testimony whereof We have signedl our names to this specification before two subscribing witnesses.
